Solar heat-collecting waste drying and screening system and method of using the same

Abstract

The invention discloses a solar heat collection type garbage drying screening system and a use method thereof. The solar heat collection type garbage drying screening system includes a rectangular sealed drying bin, and a transparent heat preservation bin is provided at the port of the sealed drying bin. The cover, the sealed drying bin as a whole has an inclination angle of 5-10 degrees with the horizontal plane, and at least one cylindrical drum screen parallel to the bottom is arranged in the bin. The method includes feeding, drying and primary screening. The solar heat collection type garbage drying screening system of the present invention has simple structure and low cost. The method of using the solar heat collection type garbage drying screening system for drying treatment, using solar energy to assist drying, can use its own metabolic activities to efficiently and quickly degrade the organic substances contained in the original domestic garbage before incineration, Shorten the drying time, improve the quality of waste-derived fuel, reduce secondary pollution, and improve the resource pretreatment level of primary domestic waste.

Description

technical field [0001] The invention relates to a domestic garbage treatment system integrating garbage drying, primary screening and material delivery and a use method thereof. Background technique [0002] With the development of society and economy, the output of combustible solid waste, mainly domestic garbage, is increasing day by day in China. However, a large amount of domestic waste is disposed of in simple landfills or piled up in open landfills around cities, which not only takes up a lot of land, causes groundwater and odor pollution around the landfill, but also wastes a lot of energy. From an energy point of view, the development potential of converting waste into heat and making full use of it is huge. However, at present, domestic primary waste generally has a high moisture content, low calorific value and poor uniformity. Direct incineration of these primary wet wastes with complex components will bring problems such as unstable combustion, low combustion e...

Problems solved by technology

However, the existing domestic waste biological drying system is complicated and the investment cost is high

In addition, biological drying is often limited by the nature of the raw waste material itself. Once the content of perishable organic matter is low or the nutrients in it are unbalanced, it will be difficult to generate sufficient biological heat, and then the drying of the entire system will not be able to effectively treat the raw waste. deal with
